The MZC-304F meter performs short circuit loop measurements with a resolution of 0.01 Ω, also in the case of measurements in networks protected with RCD switches. With a backlit keyboard and display, the device can be used even in low light. The device has a sealed casing with IP67 protection, which is characterised by excellent resistance and ensures smooth operation even under adverse environmental conditions.\u003c\/p\u003e\n\u003cp\u003eThe device meets the requirements set out in standard EN 61557.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv class=\"html-content sonel-content clearfix description-item\"\u003e\n\u003cdiv class=\"description-item-label\"\u003e\n\u003cp\u003e\u003cstrong\u003eCapabilities\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"description-item-content\"\u003e\n\u003cul\u003e\n\u003cli\u003eFault loop impedance measurement with 0.01 Ω resolution.\u003c\/li\u003e\n\u003cli\u003eLow-current impedance measurement in circuits protected by RCD ≥ 30mA with 0.01 Ω resolution (range of 180...270 V)\u003c\/li\u003e\n\u003cli\u003eOperates in networks with voltages 220\/380 V, 230 V\/400 V, 240\/415 V (operating range 180...460 V)\u003c\/li\u003e\n\u003cli\u003eOperating voltage range: 180…270 V (for Z\u003csub\u003eL-PE\u003c\/sub\u003e\u003cspan\u003e \u003c\/span\u003eand Z\u003csub\u003eL-N\u003c\/sub\u003e) and 180…460 V (for Z\u003csub\u003eL-L\u003c\/sub\u003e).\u003c\/li\u003e\n\u003cli\u003eMaximum measuring current: 7.6 A for 230 V (3x10 ms), 13.3 A for 400 V (3x10 ms).\u003c\/li\u003e\n\u003cli\u003eOperating frequency 45…65 Hz\u003c\/li\u003e\n\u003cli\u003eCalculation of I\u003csub\u003ek\u003c\/sub\u003e\u003cspan\u003e \u003c\/span\u003efault current.\u003c\/li\u003e\n\u003cli\u003eMeasurement with swapped L and N conductors.\u003c\/li\u003e\n\u003cli\u003eMeasurement of resistance (R\u003csub\u003eS\u003c\/sub\u003e) and reactance (X\u003csub\u003eS\u003c\/sub\u003e) components.\u003c\/li\u003e\n\u003cli\u003eLow-voltage measurement of continuity of circuit and resistance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"html-content sonel-content clearfix description-item\"\u003e\n\u003cdiv class=\"description-item-label\"\u003e\n\u003cp\u003e\u003cstrong\u003eAdditional features\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"description-item-content\"\u003e\n\u003cul\u003e\n\u003cli\u003eContact electrode - quick testing of proper connection of PE conductor.\u003c\/li\u003e\n\u003cli\u003eVoltage measurement 0...500 V.\u003c\/li\u003e\n\u003cli\u003eFrequency measurement 45.0...65.0 Hz.\u003c\/li\u003e\n\u003cli\u003eMemory of 990 measurement results, ability to transfer the data to a PC via Bluetooth.\u003c\/li\u003e\n\u003cli\u003ePower supply: batteries (4 x LR14) or rechargeable batteries (4 x NiMH).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"html-content sonel-content clearfix description-item\"\u003e\n\u003cdiv class=\"description-item-label\"\u003e\n\u003cp\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"description-item-content\"\u003e\n\u003cp\u003eThe instrument is dedicated to personnel performing measurements in single and multi-family buildings, office buildings, industrial plants and any other places equipped with low voltage electrical systems.
